To all whom it may concern:

Be it known that I, ALEXANDER H. HAND- LAN, Jr., a citizen of the UnitedStates of America, residing at the city of St. Louis, in the State ofMissouri, have invented certain new and useful Improvements in LanternConstructions, of which the following is a. full, clear, and exactdescription, reference being had to the accompanying drawing formingpart of this specification.

My invention relates to the construction of the lower portions oflanterns, and it has for its object, the production of such portions oflanterns at a minimum cost, and without the employment of skilled labor,while at the same time, furnishing a more secure and ethcient connectionbetween the lower parts of the lantern, namely, the base rim, the guardhoop or oil pot hoop and the oil pot pocket plate.

Figure I is a vertical section taken through the lower part of a lanternconstructed in accordance with my invention. Fig. 11 is a verticalsection taken through the lantern base rim, guard hoop, or oil pot hoopand oil pot pocket plate, with said members in the positions assumedprevious to their being clamped to each other. Fig. 111 is a viewsimilar to II, illustrating a modification. Fig. IV is a view of theparts shown in Fig. Ill after they are secured to each other. Fig. V andVI are views similar to F 111 and TV respectively illustrating anothermodification. Figs. VII and VIII are views similar to III and Vrespectively illustrating still another modification.

In the accompanying drawings: 1 designates the base rim of my lantern,see Figs. 1 and II. This base rim is in the form of an inverted dish,and it is provided with a central circular aperture 2, located in thetop of the base rim, and adapted to receive the guard hoop 3. The guardhoop 3 serves also as the oil pot hoop, but it will be hereinafterdesignated merely as the guard hoop. The guard hoop is provided aboveits lower end with an outwardly projecting annular and horizontal bead 1and it terminates at its lower end in an outturned annular flange 5.which is located beneath the bead 4 and between which and the bead is aportion of the guard hoop that occupies the central circular aperture 2in the base rim 1 when the guard hoop is introduced into the base rim.

6 is the oil pot pocket plate located beneath the guard hoop and withinthe base rim 1. This oil pot pocket plate is provided at its edge withan upturned and inturned annular flange 7 adapted to seat beneath thetop of the base rim 1 adjacent to its central circular aperture and toencircle the outturned annular flange at the lower extremity of theguard hoop 3.

In assembling the parts of my lantern that have been thus far described,the lower end of the guard hoop is introduced into the cen-' tralcircular aperture in the base rim 1, so that its bead 1 will rest uponthe upper edge of said base rim, and the outturned flange 5 of the guardhoop will occupy a position be neath the top of the base rim. The oilpot pocket plate is placed within the base rim and moved upwardlytherein, until its upturned flange 7 encircles the outturned flange 5 ofthe guard hoop. Then, by the use of a suitable implement or machine,pressure is applied to the oil pot pocket plate adjacent to its edge andthe guard hoop is held from movement during the application of suchpressure whereby the outturned flange 5 of the guard hoop and theupturned and inturned flange 7 of the oil pot pocket plate are pressedtightly to each other beneath the top of the base rim of the lantern, sothat the first named of said flanges is firmly seated between the lastnamed flange and the top of the oil pot pocket plate, as seen in Fig. l.A secure interengaging flange joint between the guard hoop and the oilpot pocket plate is thus provided, and the base rim 1 is caused to befirmly clamped between said interengaging oint and the annularhorizontal bead of the guard hoop above it, which serves as a resistancemember to )revent upward movement of the base rim on the guard hoop.After the parts have been assembled and united in the manner described,they may be dipped in a suitable soft solder whereby the interstices atthe point of connection of the parts are effectually closed.

In Figs. III and IV, I have shown a modification wherein the base rim 1is provided at its top and around its aperture with a do-wnturned andoutturned flange 1 and the guard hoop 3 is provided at its lowerextremity with an outturned flange 5- that is adapted to seat within theflange 1 of the base rim. In this construction the bead upon the guardhoop is dispensed with. 6 is the oil pot pocket plate which is providedwith the upturned and inturned flange 7 that corresponds approximatelyto the upturned and inturned flange of the oil pot pocket plate 6. Theupturned and inturned flange 7 of the oil pot pocket plate is adapted toenter into a position between the top of the base rim 1 and itsdownturned and outturned flange 1 Vhen the parts just described havebeen assembled as illustrated in Fig. III, they are subjected topressure with the result of causing the upturned and inturned flange 7of the oil pot pocket plate to become embedded between the top of thebase rim and its downturned and outturned flange 1, and the outturnedflange 5 of the guard hoop will become embedded between the downturnedand outturned flange 1 of the base rim and the top of the oil pot pocketplate, thereby producing the interengaging flange joint shown in Fig.IV.

In the modification shown in Figs. V and VI, the base rim 1 is providedat its top with an upturned and outturned flange l that surrounds thecentral circular aperture in the base rim and the guard hoop 3 isprovided at its lower extremity with an inturned flange 5. The oil potpocket plate 6 is provided at its edge with a downturned and inturnedflange 7 that is adapted to be positioned between the upturned andoutturned flange of the base rim and the inturned flange of the guardhoop. hen the parts justdescribed are subjected to pres-' sure, theinterengaging flange joint is pro duced in which the downturned andinturned flange of the oil pot pocket plate enters into the upturned andoutturned flange of the base rim and the inturned flange of the guardhoop enters into a position beneath the flange of the oil pot pocketplate, as seen in Fig. VI.

In F VII and VIII, I have shown another modification in which the baserim 1 is provided at its top with a central circul-ar aperture, but isunflanged at the location of this central circular aperture. The guardhoop 3 is provided at its lower extremity with an inturned flange 5 thatis adapted to occupy a posit-ion above the top of the base rim. The oilpot pocket plate 6 has at its upper end an upturned and outturned flange7, and is provided at its lower end with an annular bead (3 that isadapted to occupy a position beneath the top of the base rim 1*, whilethe upturi'ied and outturned flange of said oil pot pocket plateprojects upwardly above the top of the base rim and into the lower endor inturned flange of the guard hoop. In this construction the annularhead of the oil pot pocket plate serves to restrict said oil pot pocketplate from upward movement in the base rim, and the parts are unitedwhen pressure is applied to them, due to the upturned and outturnedflange of the oil pot pocket plate being pressed outwardly anddownwardly with the result of causing the inturned flange at the lowerend of the guard hoop to be clamped between the upturned and outturnedflange of the oil pot pocket plate and the top of the base rim 1 as seenin Fig. VIII.

1. In a lantern, a base rim, a guard hoop having a flange for connectionwith said base rim, and an oil pot pocket plate; all of said parts beingconnected by an interengaging flange joint, substantially as set forth.

2. In a lantern, a base rim having a central circular aperture, a guardhoop fitting in the central circular aperture in said base rim andprovided with a flange, and an oil pot pocket plate having a flangefitted to the flange of said guard hoop and having an interengagingflange joint connection therewith, substantially as set forth.

8. In a lantern, a base rim having a central circular aperture, a guardhoop fitting in the central circular aperture in said base rim andhaving a bead above the central circular aperture, and a flange beneaththe central circular aperture, and an oil pot pocket plate having aflange provided with an interengaging flange joint connection to theflange of said guard hoop, substantially as set forth.
